Ageing, justice and resource allocation

Ageing and typical survivorship curves result from optimal resource allocation

Ageing is a general feature of higher organisms. Evolutionary theories of ageing rest on a gradual decline of fitness sensitivity to changes in survival and fecundity with age, so traits expressed late in life are less favoured by natural selection than those expressed early in life. From the life-history perspective, ageing may result from a scheme of optimal resource allocation in which inves...

Economic and Effectiveness Evaluation Analysis of Some Resource Allocation Procedures

Review of theoretical models for cost-effectiveness and of procedures currently being used by different levels of decision makers to evaluate the projects or alternatives is the main objective of this article. To come to some conclusion that which theoretical model would be more effective to be applied for allocating the limited resources among different projects. the performance evaluation pro...

Bicriteria Resource Allocation Problem in Pert Networks

We develop a bicriteria model for the resource allocation problem in PERT networks, in which the total direct costs of the project as the first objective, and the mean of project completion time as the second objective are minimized. The activity durations are assumed to be independent random variables with either exponential or Erlang distributions, in which the mean of each activity duration ...

Justice and allocation of medical resources.

In one of a series of short articles on philosophical medical ethics, Gillon examines the principle of justice as it applies to adjudicating competing claims for the distribution of scarce medical resources. He describes Aristotle's theory of justice--with its demands of formal equity, impartiality, and fairness--and then considers various substantive criteria that have been proposed to justif...
